Registration method for visual navigation of dental implant surgery and electronic device

Abstract

The invention discloses a registration method for visual navigation of dental implant surgery and an electronic device. The method includes the following steps: obtaining a target tooth registration 3D model, a target tooth registration solid model and a second target tooth model; obtaining the position and attitude matrix of the target tooth registration 3D model in a virtual coordinate system according to the coordinates of at least three points on a base 3D model obtained after the registration of the target tooth registration 3D model in the virtual coordinate system; and installing the target tooth registration solid model on a registration standard board, obtaining the position and attitude matrix of the target tooth registration solid model in a visual coordinate system according tothree optical markers and the points on the target tooth registration solid model corresponding to the at least three points, and obtaining the corresponding relationship between the virtual coordinate system and the visual coordinate system according to the two position and attitude matrixes. By using the registration method for visual navigation of dental implant surgery and the electronic device provided by the invention, the accuracy of registration between the two coordinate systems is improved.

Description

technical field [0001] The invention relates to the technical field of medical robots, in particular to a registration method and electronic equipment for visual navigation of dental implant surgery. Background technique [0002] The intelligent and high-precision characteristics of the robot make it have unique advantages in the application of stomatology. Due to the fine and complex structure in the oral cavity, it is necessary to use the positioning and navigation system of the robot to perform precise positioning to improve the treatment effect. [0003] Before the dental implant surgery, the doctor plans the surgical path on the 3D model based on the reconstruction of the patient's CT image. During the operation, the virtual space coordinate system and the visual coordinate system need to be registered. The virtual space coordinate system is the CT image reconstruction of the patient's dentition The coordinate system where the 3D model of the robot is located, the visua...

AI Technical Summary

Problems solved by technology

The accuracy of registration using anatomical landmarks is low, while using artificial landmarks for registration needs to be implanted in the patient's alveolar process or jawbone, which will cause unnecessary trauma or even infection to the patient
